Propylene Glycol Butyl Ether

PnB Glycol Ether

Technical grade

PnB glycol ether is a fast evaporating, hydrophobic solvent which is extensively used in heavy-duty cleaning formulations. It does an excellent job of solvating and coupling hydrophobic greases and oils in household as well as industrial formulations. It is partly water soluble and miscible with most organic solvents. PnB glycol ether also provides excellent surface-tension lowering ability. In coatings PnB offers good coalescing ability in systems requiring fast evaporation

Uses for Propylene Glycol Butyl Ether

  • Coupling agent and solvent in household and industrial cleaners, grease and paint removers, metal cleaners, and hard surface cleaners.
  • Effective coupling agent and efficient solvent for water-reducible coatings.
  • Effective coalescent for lowering minimum film formation temperature (MFFT) in water-borne latex coatings.
  • Active solvent for solvent-based coatings.
  • Chemical intermediate for the production of epoxides, acid ester derivatives, solvents, and plasticizers.
  • Effective coupling agent in water based agricultural formulations.
